Achievements come in many different forms. Sometimes we tend to underestimate the value of our own achievements and it is just a matter of learning how to identify them. For each position on your resume, consider your role and think back on what you did well for that position.
For example, did you solve a problem? Did you complete a project ahead of schedule? Did you receive commendations from clients? These are all achievements that you can put on your resume.
If you’re applying for your first job and haven’t built any proper professional experience, think about it in terms of your academic achievements. Have you completed any challenging assignments that you are particularly proud of, or did you take part in any extra-curricular activities, projects or duties?
